United States Patent Office 3,218,775 Patented Nov. 23, 1965 3,218,775COLUMN STRUCTURE ERECTION METHOD Thomas J. Jackson, R0. Box 992,Robstown, Tex. Filed Sept. 7, 1960, Ser. No. 54,527 3 Claims. (Cl.52-745) This invention relates to a method for erecting columnstructures in building construction and the apparatus used inconjunction with such erection method. The novel method of thisinvention is especially useful for the erection of a buildingconstruction as disclosed in my prior copending application Serial No.20,214, filed April 5, 1960, entitled Foundation Column, now Patent No.3,108,403, issued October 29, 1963, although not necessarily restrictedto the erection of such a building construction.

It is therefore a primary object of this invention to provide a novelmethod for erecting long and heavy column structures to therebyfacilitate and render more practical the building of various types ofstructures which would otherwise be considered impractical because ofthe difiiculties in raising such structures.

Another object of this invention is to provide a novel method forerecting column structures in a building construction by use of standardand economical equipment and also enabling more efficient assembling ofthe struc tural elements and involving a tremendous savings in time andlabor.

A still further object of this invention is to provide a novel methodfor raising long column structures for a building eliminating thebending of such long column structures that would otherwise result fromits erection.

An additional object of this invention is to provide a novel method forerecting long column structures employing a removable columnreinforcement eliminating or resisting bending of the column structurewhile being raised, said column reinforcement subsequently being removedand reused for raising other column structures adjacent to the uprightcolumns.

A still further object of this invention is to provide a removable chainshackle truss column reinforcement which involves an assemblage ofrelatively simple and dimensionally varying parts so as to provide aremovable column reinforcement of varying sizes for accom modating anydesirable column structure.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the ac oompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FIGURE 1 is a schematic perspective view of a col umn structure and roofsection in the process of being erected.

FIGURE 2 is a partial schematic perspective view of a column structureand roof section supported thereon in its erected position.

FIGURE 3 is a side elevational view of a column pivotally anchored inits horizontal position when temporarily reinforced by the reinforcementapparatus of this invention.

FIGURE 4 is an enlarged partial view of the base end of the horizontaltemporarily reinforced column illustrated in FIGURE 3.

FIGURE 5 is a partial bottom view of a portion of the temporarilyreinforced column of FIGURE 3.

FIGURE 6 is a sectional view taken through a plane indicated by sectionline 66 in FIGURE 5.

Referring now to the drawings in detail, FIGURE 3 illustrates a columnmember 10 which may constitute a portion of a column structure to beerected by means of the method and apparatus of this invention. Thecolumn 10 is to be anchored within a concrete slab 12 by means of afoundation column anchor generally indicated by reference numeral 14 ofthe type disclosed in my aforementioned prior copending applicationSerial No. 20,214. Accordingly, the column member 10 may be pivotallyraised to an upright position wherein it is rigidly anchored in theconcrete slab 12 by means of the funda-tion anchor 14. It will beobserved however in FIGURE 3, that the column member 10 is provided withthe removable chain shackle truss reinforcement generally indicated byreference numeral 16. Accordingly, as the column member 10 is pivotallyraised to its upright position, the removable reinforcement 16 willresist bending thereof. After the column member 10 has been erected, thereinforcement 16 may be removed therefrom for use on other columns.

Referring now to FIGURES 5 and 6 in particular, it will be observed thatthe removable reinforcement 16 is composed of a plurality of clampmembers generally inidca-ted by reference numeral 18. Each clamp member18 includes semi-circular sections 20 and 22 which are fitted about thecolumn member 10 which is of tubular construction. A pair of clampingbolt members 24 are therefore provided in order to clamp the clampsections 20 and 22 onto the tubular column member 10. Connected to oneof the clamp sections 22 as by welding is a stud member 26 whichincludes at its radially outer end a guiding eye portion 28. The eyeportion 28 therefore receives therein the flexible chain member 30. Itwill therefore be observed from FIGURE 3, that the stud members 26 whichare connected to the column member 10 at spaced intervals therealong bymeans of the clamps 18 progressively vary in length. The stud member 26of maximum length is therefore disposed at the center of the columnmember 10 with the stud members progressively being reduced in lengthtoward the ends of the column member 10. Accordingly, the flexible chainmember 30 .by being guided through the eye portions 28 of each of thestud members 26 and anchored at its ends by means of a pivota'l anchor32 as more clearly seen in FIGURE 4, will form a truss reinforcement forthe column member 10. It will therefore be appreciated that thereinforcement 16 is composed of clamp members 18 and stud members 26 of.diiferent lengths and numbers so as to accommodate the length of aparticular column and the load carried thereon. Therefore, in order topractice the method of this invention one need only stock clamp and studassemblies of different sizes which may be selectively assembled withthe flexible chain 30 for accommodating the different erectionrequirements.

As a result of the use of the removable reinforcement 16 for anexemplary column member 10, the column member 10 may be positioned in ahorizontal position as illustrated in FIGURE 3 before erection and therein forcement 16 applied thereto. In such horizontal position aplurality of connecting members 34 may be welded to the horizontallydisposed column member 10 so that when the column member is erected toits upright position the connecting members may then be welded to anadjacent upright column member in order to form a column structure. Itwill therefore be appreciated that much of the diflicult welding byscaffold-supported welders is eliminated to thereby effect a tremendoussaving in time and labor in erecting a building construction pursuant tothe method of this invention.

Referring now to FIGURES l and 2, the particular application of themethod of this invention will be illustrated. It will therefore beobserved in FIGURE 1, that a building set generally indicated byreference numeral 36 has been erected to a vertical position. The

building set 36 is of the type which is composed of side columnstructures 38 and 40 which are interconnected and support a truss roofsection 42. This type of welded construction is disclosed in myaforesaid prior copendring application. It will therefore be observedthat a plurality of foundation anchors 14 are employed to anchor theside column structures 38 and 40. It will also be observed that a secondset 44 is disposed adjacent to the set 36 in a horizontal positionincluding side column structures 46 and 48 interconnected by the trussroof section 50. It will also be observed that movable trussreinforcements 16 are provided on the side column structures 46 and 48.Also, a similar removable reinforcement 16 is provided between the ends52 and 54 of the roof section 50, said latter removable reinforcement 16being disposed beneath the roof section 50 and not shown in FIGURE 1.Accordingly, the set 44 in its horizontal position will be renderedperfectly rigid by the three removable reinforcements 16. It will alsobe observed in FIGURE 1, that a plurality of connecting members 34 havebeen welded to the various structural parts of the building set 44, suchwelding obviously being accomplished .with greater ease while the set 44is in its horizontal position.

It will be further observed in FIGURE 1, that a cable 56 is anchored atits opposite end-s to anchor points 58 and 60 on the building sets 36and 44, respectively. The anchor points 58 and 60 are therefore locatedat the center of the roof sections 42 and 50 of each building section.It will therefore be apparent that with the upright building set 36being held rigidly in its upright position by suitable means such asguide ropes, a lateral force may be applied to the cable 56 by means ofa gin pole 62, for example, to thereby pivotal-1y displace the buildingset 44 on its foundation anchors 14 to thereby raise the building set 44to its upright position parallel to the upright building set 36.Accordingly, as seen in FIGURE 2, the set 44 may be connected to the set36 by welding the .unwelded ends of the connecting members 34 to the set36. After the connecting members 34 have been welded and a rigid uprightstructure thereby attained, the removable reinforcements 16 are removedfrom the set 44 for subsequent use on additional building sets which maybe erected and connected to the set 44 for example. It will therefore beunderstood that the erection procedure hereinbefore described will berepeated until a complete building is erected.

From the foregoing description, the utility of the method and theapparatus will be apparent. It will therefore also be appreciated thatbuilding constructions heretofore deemed to be impractical because oferection difficulties may now be erected in order to provide moreendurable building constructions. Furthermore, as a. result of the novelmethod and apparatus column erection in general may be accomplished witha tremendous savings in time, labor and erection equipment and alsoenable reduction of difiicult welding.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown and de- 4scribed, and accordingly all suitable modifications and equivalents maybe resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A method for erecting a building structure consisting of sets of sidecolumns having first and second ends interconnected by roof sectionscomprising the steps of: raising one set of side columns andinterconnecting roof section to an upright position; assembling andanchoring said first ends of the columns of another set adjacent to thefirst end-s of said one set substantial-1y at ground level; attachingconnecting members to said other set while substantially in a horizontalposition supported by the ground adjacent said second ends of thecolumns; temporarily reinforcing the other set against bending due toerection; raising said reinforced set loaded with the connecting membersthereon to an upright position parallel to said one set; connecting theconnecting members to said one set after erection of said other set tothe upright position; and removing the temporary reinforcements from theother set.

2. The method of claim 1 wherein said other set is raised to a verticalposition by anchoring a cable to a center portion of the roof sectionthereof and applying a lateral force to the cable to pivotally displacethe other set toward the first set.

3. A method for erecting long column structures comprising the steps of:erecting a column structure; pivotally anchoring a base end of a columnsubstantially at ground level adjacent to said column structure;applying a removable truss reinforcement only to the column forresisting hen-ding thereof in an erection plane; securing connectingmeans to the temporarily reinforced column at spaced locations betweenthe base end and the opposite of the column while in a substantiallyhorizontal position supported by the ground at said opposite end;.

pivotally raising the reinforced column loaded with said connectingmeans in the erection plane to an upright position; securing theconnecting means to said column structure and thereafter removing theremovable truss reinforcement from the column.
